You are watching: Is a diamond a pure substance

The carbon atoms in diamond form a recurring 3-D tetrahedral structure that connects every atom to 4 atoms. This structure renders diamond more powerful than mixtures since a mixture walk not have actually a strong chemical bond. Therefore, you have the right to distill or filter a mixture.

Diamond is an element. It is not a compound together compounds contain numerous elements. Additionally, diamond is not a mixture because a mixture is either a systems or a mix of various elements in unlike ratios. For example, bronze is a mixture of copper and tin.

In the rest of this article, we will compare aspects with compounds, and explain the main differences in between diamond and other aspects made that carbon. Us will additionally discuss the properties of diamond, why diamonds are famous in jewelry making, and also the grading mechanism of diamonds.


What are the properties of Diamond?

Each carbon atom has actually 6 protons and also 6, 7 or 8 neutrons. Protons room the number of subatomic corpuscle in atoms and they different from neutrons due to the fact that protons have actually an electric charge and a lesser mass.

When share by the sum of protons and also neutrons, also called isotopes, a carbon atom can be carbon-12, carbon-13 or carbon-14. This total variety of isotopes is likewise the mass number of a carbon atom.

The atoms of elements made that carbon have various structural units. This distinct characteristic is called allotropes. For instance, the atom in graphite, i beg your pardon is also an aspect made the carbon, have actually a hexagon structure while the atom in diamond have actually a four-attachments 3-D structure. Hence, graphite breaks easily since the 3 bonds in its atoms do it weak and also soft.

Due to the distinction in allotropes, diamond has actually a density of 0.020 lb/in (3.515 g/cm3) when graphite’s thickness is 0.012 lb/in (2.267 g/cm3).The tetrahedral systems of diamond do it:


HardResistant to chemistry processesA poor conductor because it has actually no cost-free electrons or ionsA an excellent conductor of heat and also sound

In the complying with video, Dr. Stan Fowler breaks down the differences between graphite and also diamond:

The carbon cycle influences the development of diamonds in the Earth’s surface. The molecule of types must dissolve to type carbon. In this process, diamond gathers little traces of various other atoms, such together nitrogen. Hence, there space 4 types of diamonds, all classified by the impurities in them. Form 1a has actually a nitrogen ingredient of around 0.03% while type IIa and type IIb have nearly no traces of nitrogen.

What space the Differences between Elements and also Compounds?

An aspect is a substance created of one atom, but several elements constitute a compound. The facets in compounds have actually definite ratios, which enables each of these proportions to be expressed in a chemical formula. For example, there room specified ratios of oxygen and hydrogen in water that provide water the chemical formula H2O. Other differences between elements and also compounds are

The Total number of Elements and also Compounds

The American institute of Physics states there room 118 elements. The planet produces 94 of these elements while the remainder are created from radioactivity. On the contrary, compounds are limitless.

The Representation

A chemistry symbol to represent an facet while a chemistry formula represents a compound. For example, the chemical formula the nitrogen is N2 vice versa, diamond’s chemical symbol is C.

The habits of the elements in a Compound

The elements in a compound differ in different settings and also temperatures. Because that example, in ~ room temperature, hydrogen and oxygen space in gas form. ~ above the other hand, under the exact same circumstances, water is in fluid form.

I discovered this an easy assessment quiz that differentiates elements, compounds and mixtures.

FuseSchool additionally has a 5-minute video clip about the differences between compounds, elements and mixtures:

What room the main Uses the Diamond?

This aspect is wanted when make jewelry due to the fact that of its beauty and also its hardness. It is such crucial element the the industry developed a diamond grading system recognized as the 4Cs:

Cut – there are different diamond cuts. The most famous cuts are round, emerald, princess, heart, and oval. A diamond derives its sparkle from the high quality of that cut. Diamonds with a larger diameter have a bigger crown, which makes them appear larger. These larger diamonds might not have a heavier carat weight.

However, this study found that carob seeds execute not have a constant weight that 0.007 oz of a carat. Thus, traders might have preferred carob seeds since they were readily available and not due to the fact that they had actually a continuous weight.

With together information, you’ll understand the product specifications when looking with diamond jewelry, such together this pair of round Diamond Stud earrings. They have a carat load of over 0.5 carats, clarity that 12-13 and also H come J color. The customer reviews say the range of carat weights available make this earrings ideal gift items since you have the right to buy the carat weight you can afford.

Additionally, they space conflict-free diamonds. Castle were not mined or traded for reasons like capital rebel militia to destabilize governments. This note of top quality is a certification procedure initiated by nations that develop diamonds in southern Africa, in 2000.

In 2003, the Kimberley procedure Certification system (KPCS) came into impact to certify each gem as proof the the authenticity of its mining process and trade. 82 nations are part of the Kimberley Process, and all member nations must trade with countries that monitor the accuse of the KPCS.

The source of the diamonds also affects its worth in the market. Because that example, more buyers like diamonds mined from Canada. They take into consideration these to be conflict-free gems extracted by miners working under considerate conditions, working for diamond producers who adhere to the legislations of the trade. Canada is the 3rd largest producer that diamonds in the world. Various other producers are Russia, Botswana, south Africa and also Angola.

A diamond is also valued because of the institution that graded it. Because that example, the Gemological institute of America has actually graded diamonds because 1931.


Diamond is an aspect made of carbon and also negligible quantities of impurities and also elements choose nitrogen. As an element, it is resistant to chemical activity. The solid tetrahedral bonds in between its atoms do this gem a an excellent conductor that heat and also a bad conductor the electricity. The rarer of these gems are pure as they have actually no traces the nitrogen.

There are a range of diamond cuts, colors, and weights. The diameter identify the dimension of the crown. Many diamonds are mined in afri countries, yet Canada and also Russia are among the optimal five countries mining diamonds.
